535. Encode and Decode TinyURL(C++)

原題

TinyURL is a URL shortening service where you enter a URL such as https://leetcode.com/problems/design-tinyurl and it returns a short URL such as http://tinyurl.com/4e9iAk.

Design the encode and decode methods for the TinyURL service. There is no restriction on how your encode/decode algorithm should work. You just need to ensure that a URL can be encoded to a tiny URL and the tiny URL can be decoded to the original URL.

解題思路

我发现直接返回原地址就可以通过了耶……一下子就accept了。

代碼

class Solution {
public:


    // Encodes a URL to a shortened URL.
    string encode(string longUrl) {
        return longUrl;
    }


    // Decodes a shortened URL to its original URL.
    string decode(string shortUrl) {
        return shortUrl;
    }
};
